5.1.4 Sensor Maintenance
Sensor maintenance should be performed at regular intervals, depending on the
desired accuracy and the conditions of use. A suggested maintenance schedule is
outlined below.
1 week
•
Check the pyranometer for level and contamination. Gently clean, if
needed.
•
Visually inspect the wind sensors and radiation shield.
1 month
•
Check the rain gage funnel for debris and level.
•
Do a visual/audio inspection of the anemometer at low wind speeds.
•
Check the filter of the temperature/humidity sensor for contamination.
General Maintenance
•
An occasional cleaning of the glass on the solar panel will improve its
efficiency.
•
Check sensor leads and cables for cracking, deterioration, proper routing,
and strain relief.
•
Check the tripod or tower for structural damage, proper alignment, and for
level/plumb.
6 months
•
Clean the temperature/humidity sensor.
•
Clean the Gill Radiation Shield.
1 year
•
Replace anemometer bearings.
•
Calibrate the rain gage.
•
Calibrate the HMP45C probe.
2 years
•
Calibrate the pyranometer (some users suggest yearly).
•
Calibrate the HMP45C temperature/humidity sensor.
•
Replace the wind vane potentiometer and bearings.
4 - 5 years
•
Replace sensor cables as required.
Rain Gage Calibration Check
1.
Secure a metal can that will hold at least one quart of water.
